EDWIN WILLIAMSON, OF TALLADEGA, ALABAMA.

I ADDING AND LISTING MACHINE.

application filed December 31, 1910. Serial No. 600,357.

To all whom it may concern:

Be it known that I, EDWIN WILLIAMSON, a citizen ofthe United States,-residing at Talladega, in the county of Talladega and State of Alabama,have invented certain new and useful Improvements in Adding and ListingMachines, of which the following is a specification.

My invention relates to adding machines, and moreparticularly to amachine of this character in which is combined accumulating ortotalizing mechanism with means for listing in tabular form thesuccessive amounts registered by the'totalizing mechanism.

Among the objects of the invention are to provide a machine of this typehaving comparatively few moving parts, and which shall be simple andcompact in construction, and accurate in operation. To this end, thereis provided only two rows or series of finger keys, the keys of oneseries serving to'bring the registering and recording devices into thedesired position,,and the keys of the second series serving to actuatesuch devices after they have been shifted by the first mentioned keys.These two sets of keys I shall designate as column keys and digit keys,respectively.

With the above general objects view and to provide as far as possible,automatic mechanism for effecting the various operations, as Well as tosimplify and improve the details of construction,the invention consistsin the arrangement and combination of parts hereinafter described andclaimed, and illustrated in the accompanying drawings, in which,

Figure 1 is a front elevation of the complete machine; Fig. 2 is avertical longitudinal section through the same, parts of the mechanismbeing shown in elevation; Fig. 3 is a horizontal section through thelower part of the machine, the mechanism being shown in plan view, andparts being omitted for the sake-of clearness; Fig. 4: is a rearelevation of the machine, with the casing removed; Fig. 5 is a frontelevation of the carriage shifting mechanism, the view being takensubstantially along the line 55 of Fig. 2, looking in the direction ofthe arrow; Fig. 6 is a front elevation, on an enlarged scale, of theplaten and carriage feed mechanism, parts being shown in section;

Fig. 7 is a front elevation of the totalizer, showing it attached to aportion of the carriage frame; Fig. 8 is a detaih-d perspec tive view ofpart of the totalizer operating mechanism, hereinafter described; Fig. 9is a fragmentary side elevation, on an enlarged scale, of suchmechanism, also showing an end view of the totalizer, parts being insection; Fig. 10 is a fragmentary elevation, similar to Fig. 9, showingthe parts in shifted position; and, Fig. 11 is a plan view of themechanism shown in Fig. 9, the totalizer being omitted.

Referring to the drawing in detail, the

operating parts of my improved machine are supported by means of a mainframe, comprising two side members designated in their entirety by thecharacter lrHinged to the frame at 3 is a front door or cover 2, havinga glass frycnt 4 through which the totalizer and listing mechanism maybe seen. To the main frame are secured side plates 5 and rear plates 6,and top plate 7, hinged at 7 to the rear plate, and a front plate 8,together forming a closed casing. Supportedat the front of the machineis a table 9 provided with slots through which the operating keysproject, and which is preferably provided with the usual felt cover .10.Extending between and supported by the side members of the main frameare a pair of cross beams 11 and 12. These beams serve as tracks orrunways to support rollers 13, upon which a carriage, now to bedescribed, is mounted. It will be-observed that the track 12 is grooved.so as to prevent lateral displacement of the rollers.

The carriage consists ofoa pair of side members lt secured together bymeans of cross rods or bars 15, 15 ,as clearly shown Mounted on thecarriage at the front thereof is a totalizer; or accurnulating devicedesignated in its entirety by the reference character 16. This deviceconidesired may be employed, according to the magnitude of the numberswhich are to be added. I

Extending from the end of the totahzer i and forming a continuation ofthe central shaft thereof is a resetting rod 19, terminating in aknurled head 20, which is adapted to project through an opening in oneof the side plates of the casing so that it may be grasped by theoperator. Projecting radiallyfrom this rod adjacent the totalizer casingis a pin 21 which is normally adapted to rest in a notch formed by apair of stop shoulders 22, one of which is beveled. When it is desiredto reset the totalizer to zero the pin is withdrawn from this notch bypulling upon the rod 19. The rod may then be turned. by means of theknurled head 20 so as to carry all of the wheels back to zero in theusual manner. The construction of the totalizer above described needs nofurther description, as .it is well known and forms no part of mypresent invention.

' In order to turn the wheels of the totalizer I provide a speciallydesigned actuating device which is most clearly shown in Fig. 9. Thedevice, which is segmental in its general shape, comprises an arc-shapedrack 23, having ratchet teeth adapted to engage the teeth of the digitwheels. This rack 23 is supported at each end by means of links 24:pivoted to a plate 25, the arrangement being such that the rack andplate lie in the same .plane. Between the rack and plate is arranged aspring 27 which is coiled around a pin 27 carried by the plate 25, and

is formed with loop portions 27 and 27 arranged to straddle the oppositeedges of the rack and plate, respectively. It will be seen that thisspring serves to force the rack downwardly and backwardly as viewed inFig. 9 so as to separate the parts as far'as possible. This movement islimited by the engagement of the lower end of the rack with a lug 26,carried by the plate 25. The plate 25 is loosely mounted upon a shaftwhich extends across thev main frame of the machine and comprises a core28, and a series of sleeves 29 fitting said core, and rigidly securedthereto. cured to said shaft, and lying one on each side of the plate25, are a pair of driving members 30, each provided, at its outer end,with a notch 31 which is adapted to receive and engage a pin 32.Arranged on each side of the driving members 30 are a pair of .floatingings 34, arranged normally con- Also rigidly se-.

centric with the shaft 28, and having outwardly projecting axial flanges35 for a purpose hereinafter explained. Each of the rings 34 isprovided'with apair of ears 36, 36, arranged on diametrically opposlte sdes thereof. One'pair of these ears is rigidly connected by means of thepin 32, which passes through a slot 33 in the plate 25, while the otherpair ,of ears is connected by a' similar pin 32 which works in a slot33' formed in a corresponding ear carried by the plate 25, and extendingbetween the ears 36' Arranged to loosely engage 5 each of the axialflanges 35 is the bifurcated end of an arm'33, these arms bein rigidlysecured to a rock shaft 39 journaled in the mainframe of the machine.Also secured to this rock shaft is an arm 40 which extends forwardlythrough the front-wall of the casing, and is secured to a finger key 4.1which is capable of vertical movement through a slot in the table 9. Aspring 4:2, attached at one end to the pin 32 and at the other end toone of the cross bars "of the main frame, serves to normally hold theactuating device in the position shown in Fig. 9, with the lower edge ofthe plate 25 resting against an adjustable stop 43 carried by the mainframe.

From the foregoing description it will be observed that with the partsin the position shown in Fig. 9 the actuating device is coupled to thedriving members 30 by reason of the engagement of the pin 32 with thenotch 31, and that, therefore, when the shaft 28'is rocked, the plate 25and rack 23 are carried forward so as to operate the digit wheels of thetotalizer. It will be noted also that when the rack 23 is moved towardthe right, as shown in Fig. 9, the ratchet teeth engage the teeth of thecorresponding digit wheel and turn it, the rack being rigidly supportedby means of the lug '26. on the return stroke, however, the links 24permit the rack 23 to swing slightly downward against the tension of thespring 27, and the rack thus rides over the teeth of the digit wheelswithout turning them. It will be seen that this means of mounting therack 23 results in its being rigidly supported against movement in onedirection while being permitted to yield in the other direction, thusbeing operative only on its forward stroke. By depressing the key 11 theshaft 39 is rocked in its bearings, and the arms 38 operate to shift therings 34, together with the pin 32, up into the position shown in Fig.10, in which the pin no longer engages the notch 31. In this position itis obvious that the driving members 30 can move independent ofthe-totalizer actuating device.

In order to rock the shaft 28, 29, and thus operate the totalizer, Imount a series of levers 44 loosely upon the shaft and provide eachlever with a pin- 45 extending axially link or pull rod 47 with itscorresponding key lever 48, these key levers being arranged near thebottom of the main frame of the machine and pivoted on a cross shaft 49at the rear of the machine. At the front of the machine thesekey leversare bent upwardly at right'angles and, afterpasslng through slots in thetable 9, termmate 1n keys 50. These are the digit keys, and bear upontheir upper faces figures indicatlng the corresponding digit. As clearlyshown in Fig. 3 there are ten of these keys, the same bearing thefigures 1, 2, 3, etc. reading from left to right. It will, of course, beunderstood, however, that.there is no connection from the O key to therock shaft.

Referring to Fig. 8 it will be seen that the lugs 46 are disposed atprogressively increasing distances from the pins 45, such distanoesincreasing regularly from the lever corresponding with the 9 key to thatcor responding with the l key. The key levers 48 are all the same lengthand have the same stroke, and the levers 44 all normallyoccupy the sameangular position. It will therefore be seen that when the keycorresponding to digit 2 for example, is depressed, the c'orrespondinlever 44 will move through a considerable angle before engaging thecorrespondin lug 46 and thus rocking the shaft and moving the actuatingdevice, while by depressing the key and lever corresponding to digit 9,for instance, there will be little or no lost motion between the pin andthe lug. By virtue of this construction it will be observed that, for

equal depressions of the digit keys 50, the

rock shaft 28 and actuating device will be moved through very unequalangles, the angle being proportional to the value of the digitcorresponding with the particular key depressed. Arranged under the keylevers 48 near the front of the machine is a slotted guide plate 48 andadjacent this plate is a transverse bar 48 carrying stop screws 48 whichmay be set to limit the downward movement of the key levers to anydesired extent.

The mechanism so far described serves to actuate the totalizer after ithas been moved to the proper position. In order to shift the carriageand totalizer into the desiredrelation with the actuating device 23 Iprovide a second series of keys, 51. which I shall designate as columnkeys. .\s shown in the drawings, nine of these keys are provided, therebeing one for each of the digit wheels of the totalizer, but it will, ofcourse, be understood that any desired number may be employed. The topsof these keys are numbered 1 to 9 inclusive from right to left, asclearly shown in Fig. 3. These keys pass through slots in the table 9and are carried by a corresponding set of key levers 52, pivoted at 53to a shaft at the rear of the machine. Springs 75 extend betweeneach ofthese levers and the cross rail 12 of the main frame. Similar springsare connected with the key levers 48 and serve to hold them in normalposition.

- Secured to each of the levers 52 near th rear of the machine is a lug54, and to these lugs is adjustably secured a set of verticallyextending links or rods 55, which pass loosely through apertured pins57, carried by a bell crank lever 58, pivoted at 59 to a lug 60 securedto the main frame. To the other end of the bell crank lever 58 ispivoted at 61 a link 62, which is pivoted at its other end at 63 to thelower end of a lever 64, pivoted at 65 to a lug 66 carried by the mainframe. To the upper end of the lever 64 is pivoted, at 67, a bar or link68, the other end of which is attached at 69 to the lower side of thecarriage frame 14. It will therefore be observed that when any of thekey levers 52 are depressed they serve, through the medium of the links55, to rock the bell crank 58 on its pivot 59 and thus pull the carriageto the left as viewed in Fig. '5, or to the right as seen in Fig. 4. Itwill also be observed that in order to permit freedom of movement thereis considerable lost motion between the heads 56 of the rods 55 and thepins 57.

It will be noted that the pins 57 are arranged at progressivelyincreasing distances from the pivot point 59 of the bell crank levercorresponding with column 1 atthe right of the machine as viewed in Fig.5, being nearest to the pivot point 59, and that connected with keylever corresponding with 'lever 58, the rod connecting with thekeycolumn 9, being most remote. A spring drum 70 is mounted in fixedlugs 72 and is provided with a, pawl or ratchet tension regulatingdevice 71. A strap. 73 passes around the drum and is secured at its endto the carriage frame 14, as indicated at 74. This drum normally tendsto hold the carriage in the position shown in Fig. 5,- and when anycolumn key is depressed the mechanism acting through bell crank lever 58and link 68 serves to move the carriage to the left as viewed in Fig. 5against the tension of the spring drum, so as to bring the correspondingdigit wheel of the totalizer into cooperative relation with theactuating device. In the normal position of the parts the digit wheelcorresponding to the ninth column is opposite the actuating device andit will therefore be seen that in order to bring the first column wheelinto position, it is necessary to move the carriage through its entirerange. Hence the necesslty of connecting which, as will be seen i thebell crank lever 87 is a with a spring 93 bearing thereon,

spring serves to urge in transverse enter 4 notches 81 her being added,

to the pivot point 59, of I and the other key levers at correspondinglyincreasing distances therefrom.

In only to more accurately position the totalizer relative to theactuating device and to stop the'carriag e precisely at the desiredpoint .when it is moved as above described, by means of the column keys,I provide at the rear of the machine a series of stop fin gers 76. Asclearly shown in Fig. 3, these fin ers are pivoted at one end to a shaft77 an are provided at their free ends with portions 78 bent at rightangles to the bodies of the fingers, and with downwardly turned lugs 80projecting from the bottoms of these bent portions. These lugs 80 arearranged alinement and are adapted to in a rack secured to the mainframe. A lug 82 is rigidly secured to the carriage frame 14 and isadapted to abut against the inturned portion 78 ofany one of thefingers, the engagement of the corresponding lug 80 with the fixed rackserving 25- to render that particular finger absolutely rigid so as towithstand the impact of the carriage. The fingers 76 are connected withthe corresponding column key levers by meansof links or rod 83, asclearly shown in Fig. 4:, the arrangement being such that when anyparticular column key is depressed to shift the carriage, thecorresponding stop finger is lowered so as to engage the lug 82 and stopthe carriage accurately at the proper point. p

In addition to the above described means for shifting the carriage tothe desired point for registering the first figure of the numit isnecessary to provide means for automatically moving the totalizerstep-by-step as the digit keys are operated, so that the successivedigit wheels may be brought into position to register the other figuresof the number. To this end, I provide a U-shaped frame 84, and pivot thefree ends of the legs to each end of the shaft 49. Extending across thisframe transversely of the machine is arranged a crossbar 85 from aninspection of Fig. 2, lies just beneath the key levers 48, so that whenany of these levers are depressed, they will carry with them the crossbar 85 and frame 84, causing it to pivot about the shaft 49. Extendingupwardly. from. the cross bar 85 and pivoted thereto, is a pull rod 86,which is connected at its upper end to one arm of a bell crank lever 87pivoted at v88 to a cross bar 1 of the main frame. To the other end ofthis lever is connected one end of a stout helical spring 89, the otherend of which is attached to a fixed bracket '90. Also pivoted at 92 tothe upper end of pawl 91, arranged which the end of the pawl 1 close 1into engagement with a rack 91 secured to the carriage frame. from theside of the pawl 91 is a wing 95, which is normally just out ofengagement with the top of a pin 96, set into a rack 97, pivoted at 98to the rack 94. Pivotally mounted on a lug 100, secured to the bar 1?,is a pawl 99 which is urged by a light spring 101 into engagement withthe teeth of the rack 97. It will be noted that the ratchet teeth of thetwo racks 94c and 97 face in opposite directions.

Near the right hand end of the pivoted rack 97 is anotch 102 which isnormally adapted to rest on a pin 103 carried by the rack bar 94 of thecarriage, and by this means the rack bar 97 is supported in the positionshown in the drawings. Depending from the lower side of the rack bar 97adjacent its end, is a lug 104. This lug is adapted to be engaged attimes by a pawl 105 pivoted to-the free end of a lever 106, which, inturn, is pivoted at of the machine. A leaf spring 108 bears against thelower end of the pawl 105, and yieldingly maintains it in the positionshown in Fig. 6. A spring 109 is attached at one end to the lever 106and at the other said lever up lever is controlled in its movements bymeans of a pull rod 110 which is pivotally secured thereto andwhich isattache d at its lower end to the bar 85.

,A hook 111 is pivoted to the carriage frame at 113, and is adapted toengage underneath the projecting end 112 of the rack bar 97 after suchbar'has been lifted as hereinafter described. This hook is urged towardthe rack bar by means of a light spring, and is provided with a tailpiece 114 projecting at an angle to the body of the hook and so locatedas to be engaged by a stud 115 secured to the main frame of the machine,when the carriage is at the right hand limit of its travel.

In order to make a printed record of the numbers as they are registeredon the totalizer, I provide a series of type bars 116, (FigQ2), pivotedat 117 to a support, and connected by means of suitable mechanism 118,119, 120 to the digit key levers 48.

against a platen 121 mounted on a shaft 121 in the carriage frame, whichshaft is 'provided at its end with a knurled head 121 by means of whichthe carriage may be turned, the type, on their way to the platen,engaging a suitable inking mechanism, such as a freely suspended inkingrollei 122. A reel 123 secured to a shaft 12 1, which lies in bearingnotches 125 in the carria elframe, carries a strip of paper 126 which,clearly shown in Fig. 2, is carriedaround tlfe platen 121, underneaththe rod 15, and out through 107 to the main frame end to the main frame1, and serves to hold in the position shown. This- These type, bars areadapted to strike' Extending laterallya slot-in the top of the casing, aserrated cutter 126 being located adjacent the slot for' "convenientlysevering the strip. The .usual spring arms 127 embrace the platen andguide the strip thereover. At the right hand endof the platen isarranged an annular rack or ratchet wheel 128 adapted to be engaged bya' spring pressed pawl 129, mounted on a stud 130, carried by a lever131, pivoted at 132 to the carriage frame and provided with a projectingtail 'piece 133, which is arranged to impinge against a stud 134,secured to the main frame of the machine. 7

The operation of the carriage mechanism is as follows: Each time that adigit key is depressed the bell crank lever'87 is rocked by means of thepull rod 86'and draws the awl 91 back so that it engages another notchof the rack 94. When the key is released the spring 89 returns the bellcrank 87 to-normal position, and in so doing, "moves the rack 94 andcarriage through the space of one ratchet tooth. This operation isrepeated, the pawl 99 serving to hold the carriage in; shifted positionagainst the tension of the spring drum. After the units wheel of thetotalizer has been actuated, the pawl 105, which is vibrated up and downat every stroke of a digit key, engages under the lug 104, and lifts therack bar 97 so that the hook 111 engages the projecting end 112 andholds the bar in raised position. In this position the pawl 99 no longeren- 36 gages the teeth of the rack, being held by a pin 99*, while thepin 96, engaging the wing 95, lifts the pawl 91 out of engagement withthe rack 94. This leaves the carriage free and it is thereupon autmatically 40 returned by the spring. drum to its extreme right handposition. As it reaches this position, the tail.114;of the hook 111strikes the stud 115 and is thereby rocked on its pivot, thus releasingthe rack bar 97 and allowing it to again fall to the position shown inthe drawings. At the same'time the tail 133 of the lever 131 engages thestud 134 and is thereby rocked on its pivot 132 in such a manner as tocause the pawl 129 to drive the ratchet wheel 128 a space of one tooth,thus automatically turning the platen and shifting the paper strip tothe extent of a line space. The platen is held in shifted position bythe engagement of a spring pressed roller 136 with a toothed wheel 135.as is usual.

The operation of the machine as a whole will now be readily understood.Suppose, for example. that the first number to be listed is 2549.- Thisis a four place num- MR1. and th refore the first digit wheel to beoperated will be in the fourth column. The

first act of the operator therefore is to depress column key No. 4. Thisserves to shift the carriage to such a position that the fourth digitwheel of the totalizer is brought opposite the actuating rack 23, andthe carriage is accurately stopped in this position by means of theengagement of the lug 82 with the corresponding stop finger 76. The nextact of the operator is to depress digit key bearing the numeral 2. vThis has the effect of'rocking the shaft 28 and thus moving the rack 23through such an angle as will cause it to move the digit wheel of thetotalizer so that the numeral 2 will appear at the sight openin As thisdigit key is released the pawl 91 s ifts the carriage so as to bring thenext digit wheel of the totalizer opposite the actuating device. Thedigit keys numbered 5 4, and 9 are then, all in the order named,consecutively depressed, and upon each depression the rock shaft andactuating device are moved through such an angle as will bring thecorresponding numeral on the respective digit wheel of the totalizerinto view at the sight opening. As the last digit key is released thetrip mechanism automatically disen-' gages the rack bars of the carriagefrom the pawls' and the spring drum draws the carriage to the right,thus bringing into play the pawl restoring mechanism and the linespacingmechanism above described, and the machine is ready for recording thenext number. We will suppose that this number is 73,862. As this is afive place number column key numbered 5 is first depressed so as tobring the fifth digit wheel of the totalizer into operative positionrelative to the actuating device. The five properdigit keys are thendepressed one after another, and the number so recorded is automaticallyadded by the totalizer to that previously registered, the figuresvisible through the sight opening of the totalizer the sum of the twonumbers so far listed. In the same way any desired number of items maybe registered one after the other, and at the same time these items arelisted by the printing mechanism upon the strip of paper 126. After,having listed the last item, the total may be read from the totalizer,and, if it is desired to record this total upon the paper, the key 41 isdepressed, thus disconnecting the totalizer actuating device from therock shaft and permitting the digit keys to be used to operate theprinting mechanism while the totalizer remains at rest.

. It will thus be seen that I have provided a combined adding andrecording machine which requires a minimum number of manual operationsand which has comparatively few moving parts, and it is thought that themany advantages of my improved machine will be readily appreciated bythose familiar. with such matters.
